ADU regulations in Utah can vary significantly depending on the specific city or county you live in. There’s no single statewide rule governing ADU placement. Instead, local zoning laws and ordinances determine where and how ADUs can be built or placed.

Generally speaking, for most areas that allow ADUs in Utah:

  1. The ADU must typically be on the same lot as the primary residence.
  2. It’s usually required to be in the backyard or side yard, not in front of the main house.
  3. There are often setback requirements (minimum distances from property lines).
  4. The ADU may need to meet certain size restrictions relative to the main house and lot size.

To get specific, accurate information for your situation, you’ll need to:

  1. Check with your local city or county planning department.
  2. Review your area’s zoning laws and ordinances.
  3. Possibly consult with a local real estate attorney or zoning expert.

Some Utah cities and counties are more ADU-friendly than others. 

Getting utilities for a tiny home depends on several factors, including whether your tiny home is on wheels (like an RV) or on a foundation, and local regulations. Here’s a general overview of how you can set up utilities for your tiny home:

  1. Electricity:
    • Grid connection: If possible, connect to the local power grid. This usually requires working with the local utility company and may need professional installation.
    • Solar power: Many tiny homes use solar panels with battery storage. This is especially useful for off-grid living or as a supplement to grid power.
    • Generator: As a backup or primary source in remote locations.
  2. Water:
    • Municipal water: If available, connect to the local water supply. This typically requires permits and professional installation.
    • Well water: For rural areas, drilling a well might be an option.
    • Rainwater collection: Some tiny home owners use rainwater catchment systems, but check local regulations as this isn’t always permitted.
  3. Sewage:
    • Septic system: For permanent tiny homes, a small septic system might be required.
    • Composting toilet: A popular off-grid solution, but check if it’s allowed in your area.
    • Municipal sewer: If available, you can connect to the local sewer system.
  4. Internet/Phone:
    • Wired connection: Similar to traditional homes if you’re in a serviced area.
    • Cellular data: Many tiny home dwellers use cellular hotspots or boosters.
    • Satellite internet: An option for remote locations.
  5. Heating/Cooling:
    • Electric: Mini-split systems are popular for their efficiency.
    • Propane: Often used for heating and cooking in off-grid setups.
    • Wood stove: For heating in suitable climates and if local regulations allow.

Key considerations:

  1. Local regulations: Check with your local planning department about requirements for utility hookups.
  2. Professional help: For safety and code compliance, consider hiring professionals for installations, especially for electrical and plumbing work.
  3. Permits: You’ll likely need permits for utility connections, especially for permanent structures.
  4. Location: Your options may vary greatly depending on whether you’re in an urban, suburban, or rural area.
  5. Cost: Factor in both initial setup costs and ongoing utility expenses in your budget.
  6. Efficiency: Due to size constraints, focus on energy-efficient appliances and systems to minimize utility usage and costs.
